# Fortitude

> CodeRabbit's guide to Fortitude.

[Fortitude](https://github.com/PlasmaFAIR/fortitude) is a Fortran linter, written in Rust. It's inspired by Ruff and provides blazingly fast linting for Fortran code.

## Files

Fortitude will run on files with the following extensions:

* `.f90`, `.F90`
* `.f95`, `.F95`
* `.f03`, `.F03`
* `.f08`, `.F08`
* `.f18`, `.F18`
* `.f23`, `.F23`

## When we skip Fortitude

CodeRabbit will skip running Fortitude when:

* No Fortran files are found in the pull request.
* When Fortitude is already running in GitHub workflows.
